Huge cache of seeds left behind, what to do?

For discussion about long time seed storage please use this topic:

How do *you* store your seeds?

Fully acknowledging that this is covered in the GrowFAQ, how do you go about storing your prized beans, particularly if you only have a few beans for a particular strain to begin with? I figure I’ll get a few years of viability using a mason jar on a bookshelf with a little bit of desiccant, but would love to hear other approaches, cautionary tales, and/or glowing success stories.

Thanks.
